Title: Cognitive Conflict
and Control in Moral Judgment
Abstract:
Traditional
theories of moral psychology emphasize
reasoning and
“higher cognition,” while more recent work
emphasizes the
role of emotion. I will present behavioral and
brain imaging
data that support a model of moral judgment
according to
which both “cognitive” and emotional processes
play crucial and
sometimes mutually competitive roles. I will
discuss a
replication and extension of a previous finding that
judgments in
response to “personal” moral dilemmas involve
increased
social-emotional processing while judgments in
response to
“impersonal” moral dilemmas involve increased
“cognitive”
processing. Further results indicate that brain
regions
associated with cognitive control are recruited to
resolve
difficult personal moral dilemmas in which utilitarian
values require
personal moral violations. I will also discuss a
brain region in
the right anterior prefrontal cortex that tracks
inter-trial
differences in moral judgment behavior, exhibiting
greater activity
for utilitarian, as compared to anti-utilitarian,
judgments.
I interpret these data to suggest that the
controversy
surrounding utilitarian moral philosophy may
reflect an
underlying tension between competing cognitive
subsystems in
the brain.
